Hello everyone. I just encountered new problem. before this my jasper report is okay. but then i changed the directory of my file but moving my project into a new folder. sub-folder in my project. im using netbaens and using jsp. before this, there is no problem at all to generate the report, but then yesterday, after i did the moving all files, when i try to generate the report, it return error:null. i have check all libraries and everthing. im using jdk 7. my jasper report plug in is version 5.6.0 and it is the same as my jasperreport.jar 5.6.0. i have tested all the path at my path which something like this File reportFile = new File(application.getRealPath("..//reports//test.jasper")); i have tried so many time changed it to many possible path but is seems to get error here is the full coding to generate the report <%@page import="Config.Config"%><%@page import="dBConn.Conn"%><%@page import="java.io.*"%> <%@page import="java.sql.Connection"%> <%@page import="java.sql.DriverManager"%><%@page import="java.util.HashMap"%><%@page import="java.util.Map"%><%@page import="net.sf.jasperreports.engine.*"%><%@page import="main.RMIConnector"%><%@page import="java.util.ArrayList"%> <%@page contentType="text/html" pageEncoding="UTF-8"%><!DOCTYPE html><html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title>JSP Page</title> </head> <body> <% try { Class.forName("com.mysql.jdbc.Driver").newInstance(); Connection conn = DriverManager.getConnection("jdbc:mysql://10.73.32.200:3306/emedica?zeroDateTimeBehavior=convertToNull", "root", "qwerty"); File reportFile = new File(application.getRealPath("..//reports//test.jasper")); Map map = new HashMap(); byte[] bytes = JasperRunManager.runReportToPdf(reportFile.getPath(),map,conn); response.setContentType("application/pdf"); response.setContentLength(bytes.length); ServletOutputStream outStream = response.getOutputStream(); outStream.write(bytes, 0, bytes.length); outStream.flush(); outStream.close(); } catch (Exception ex) { out.println("Error: " + ex.getMessage()); } %> </body></html> i think my main problem is the path, anyone has idea?thanks
